nl2ledger

Natural language bookkeeping — Claude parses amounts, categories, and timestamps from your input and appends structured entries to a QianJi CSV ledger.

Features

• Chinese, English, or mixed-language input
• Auto-detects amount, merchant, and category
• Multiple entries in one sentence (comma / pause-mark separated)
• Relative time expressions (yesterday, last Friday, 10am…)
• Preview before writing — no accidental entries

CSV File

Place your QianJi CSV file in the project root:

• Export existing data from the QianJi App, or
• Create a blank CSV with only the header row — see skills/nl2ledger/sample/QianJi_sample.csv for the format

Usage

After installation, just type in Claude Code:

午饭麦当劳25块

咖啡18，打车32

昨天晚饭西贝89

lunch 35, coffee 18

Claude will parse, show a preview, and write to CSV upon confirmation.

Customization

• Category rules: Edit references/category_map.md to add your own merchants and spending habits
• Recorder name: Change the default in category_map.md (Default Values section) and scripts/append_entry.py (--recorder)
• Default account: Same files, change the 账户1 default

Note: The category rules and special rules (merchant names, tags, etc.) in this repo are example configurations. Customize them to match your own habits.
